Most do the shots on Friday evenings,i did anyway from between 6 and 9 pm,i just relaxed all weekend and by Monday i was ready to roll
Just as "justme53" said, there is no set time and, if necessary, you can change that day and time. I used to do it on Tuesdays, between 6-7, depending on when I finished dinner. I always do it on a full tummy. Because of a change in my work schedule and that I always want to do the injuection the evening prior to my days off, this week I did it on Monday at 7, and next week I will do it on Sunday, which will be my permanent day. Having Monday and Tuesdays off now, if I have any side effects from the injection I won't have to worry about missing work.
Good luck
There isn't a set time, per se, but once you pick a time that you think will work best for you, you need to stick with it. I do mine between Fridays 7-8 pm and it works out pretty well. There was an interesting thread on this very subject that another forum member was also trying to find...people listed their shot dates/times and when, if at all, sx popped up. It was an interesting read and ALOT of variations.
